Objective:
To develop high yielding drought and heat tolerant cultivars adapted to Missouri and other drought-prone U.S. environments.

Approach:
A broad range of soybean germplasm will be screened for rooting dept, root length density, water use efficiency, and response to high temperatures. Complementing greenhouse and field experiments will be conducted to examine these traits. Field experiments will be employed to evaluate the drought tolerance of genotypes deemed promising as a consequence of the large-scale screening.
